Tevo Tornado Bed Screw Bushing

My fix for bed adjustment screws turning when leveling the bed as well as potential unwanted bed movement on my Tevo Tornado. The fit is snug (as it needs to be). Insert the bushing then insert the screw into the bushing with an allen wrench. Problem solved. UPDATE! ... I did not take the clearance of the print head into account so there is some contact with the screws when printing items that require the entire print bed. The simple solution is to simply install the bushings from the bottom of the print bed.
